Cryotherapy is used to treat many types of skin lesions including sun damage, harmless skin growths and viral warts. Liquid nitrogen is administered from a spray canister. Cryotherapy does not require a local anaesthetic as pain is usually mild and short lived (although this does vary between individuals and according to the body site being treated). The procedure itself lasts a matter of seconds. The frozen skin becomes white and takes one to two minutes to thaw back to normal skin temperature. It may be repeated up to 3 times at a single site.
Treatment is likely to produce a reaction similar to a burn. The skin may look red, swell, or blister. Redness may not be apparent in people with darker skin. After a few days, a scab will form, and this will take a few weeks to fall off depending on the site (occasionally a little longer, especially on the legs where healing is slow).
